It is limited to around 600 addresses, it’s already useless.

Well, 600 is probably more websites than most people ever use in a decade.

Can anyone explain why in the world they would use an electroluminescent light instead of a simple LED?

someone in the comments theorized it was at first supposed to be a full-fledged front light but the design changed and they just used whatever hardware was already there to power the logo

You don't use EL as a "full fledged front light", they don't have the lumen output and need a lot of support (high voltage) to produce what they do.

by hardware I meant the transformer to which the EL was connected.

The transformer is only there for the el. You'd drive the led from a transistor and the 12V supply (like Seth did here)

In the video you can see that the LED lights the logo less evenly than the EL lighting. While that's not important at all, this might be the reason behind this odd choice

Nit: the verification code check shouldn't be case sensitive.

Why is this relevant today?

I think it actually is even more relevant today than 10 years ago, as the only real production use case I can imagine for it is specialized industrial software written only for XP that no one wants to update to w10 because of the risk of breaking production but which are running on a not supported anymore OS full of vulnerabilities. If really ReactOS achieves parity then that's a possible niche.

That was the argument back in the day too. For people/devices not looking to run Windows XP/Vista.

I don't think the metric has ever changed. What has is the scope as Microsoft continues to chug along. But, I believe, their goal is still primarily some hybrid of Win98/Win2K compatibility.

I remember seeing laser cutter drivers which only ran on Windows XP, but the cutters themselves were still in use and worked great.

For (ham) radio programming software which often only supports windows, getting the programmer working on reactOS seems like a win.

I think OP means, this project is very old, what's new about it?

It runs btrfs, if you like to live dangerously.

When was it relevant?

Same as Haiku

Well done.

Good.

My site scores a 0.

I think that’s good, right?

I’m not.

Oh god.
